摘要
基坑变形监测工作中,由于变形体发生位移变形的影响因素多种多样,样本数据特征不尽相同等,因此如何选择合理数学模型对变形体的形变趋势、形变量值进行准确预报成为一个工程难点。介绍了自回归分析模型的原理及建模步骤,并结合实际工程案例进行数据预报试验分析,得出该模型的适用条件,为类似工程提供参考。
Since the displacement and deformation of deformable body are affected by various factors and sample data varies in features,to choose a reasonable mathematical model to predict the deformation date and trend has become tough in the work of foundation pits deformation monitoring.The principles and modeling steps of the autoregressive analysis model are introduced,and its applicable conditions are analyzed based on a data prediction test of an actual engineering cases in order to provide references for similar projects.
